'7 indicates a bracket, carried by the base 2 and provided with bearingsfor one end of a driving shaft 7".

7 indicates a Worm or screw secured to the shaft 7 and meshing withthe'worm gear 7 to continuously drive the latter.

7" indicates an auxiliary support, adapted to be fixed to the floor 1.This support is provided with suitable hearings to receive and supportthe opposite end of the shaft ,7?

7 indicates a motor, of any suitable type, which, through suitablegearing indicated as a whole at 7, transmits motion to the shaft 7. Aswill be clearly understood from the drawings, the gearing '7 and theworm 7 and the worm screw 7 serve as reduction gearing, whereby thespeed of the rotary member The carrier 5 and hub 5" 5, as compared withthat of the motor 7, is relatively slow.

The brackets 5 are preferably arranged to incline or extend outwardly soas to pr0- vide supports for a table 5 of relatively large size, theirfree ends being horizontal in order to support the table in a horizontalplane. The table or annular support 5 preferably comprises a series ofarc sections 5 arranged end to endand each fian ed along its oppositeside edges to strengthen it. The sections of the table 5 are preferablybolted to the brackets 5 in a Well known manner.

At oneside and between the plate 48* and rim 4*, the walls of the valve member4 are thickened and formed with two ducts 4", 4. The duct 4:" serves asthe conduit for the liquid as it flows to the vessels 8, its inner endopening upwardly centrally of the valve member 4 and its opposite orouter end leading through the rim 4". The duct 4, conducts the liquidthrough the valve member when a vessel 8 is emptying, its receiving endor port leading through the rim 4", and preferably adjacent to theportof the duct 4", and its opposite or discharge port opening downwardly asshown in the drawings. The valve seat element 10 preferably comprises aring member formed with a series ofgpenings, 10, correspending in numberto the number of holdcrs or vessels 8 and each adapted to registersuccessively with the portsof the ducts 4, 4, in the member 4 as saidring member rotates thereon. The inner wall of the ring member is shapedto snugly fit the outer conical wall of the member 4 to prevent leakageof the liquid.

10 indicates a series of pipe sections, preferably formed integral withthe ring memher and extending radially therefrom, there being a pipesection for each opening 10". The function of the pipe sections will belater described.

The vessels 8 may each comprise inner and outer walls to form a spacebetween them. This space may be filled with cork, as shown at 8, or someother non-conductor of heat to provide a suitable insulating jacket.Each of said vessels is preferably provided with a detachable cover 8,and a duct 8 in its bottom, a suitable pipe section 8 being imepoeprovided for said duct and adapted for conveying the liquid to and fromthe vessel as will be later described.

8 indicates a flanged ring secured to the outer wall of each vessel 8.As will be understood from the drawings, when a vessel 8 is inserted inan opening 5 the flange of the ring 8 will engage with the upper surfaceof the table 5 and serve to maintain the vessel 8 t-l'iereon. Thisconstruction serves to support the vessels in upright position and topermit their removal at will for cleenin or other purposes.

9 in icates a receiving chamberpreferably arranged substantially axiallyof the holders 8 and slightly elevated relative thereto to permit theflow of the liquid by gravity to the holders. The chamber 9 is rovidedwith a suitable cover through which extends the discharge end of a pipe(1, which conducts the liquid in a substantially continuous and uniformmanner from the liquid trough or discharge duct of the heater A to thechamber 9 of the dis. tributing and holding apparatus l). The chamber 9is preferably formed in two parts, an outer member 9, and. an innermember 9*, between which is provided a suitable insulating jacket 9. Thejacket ti serves t maintain the liquid in its heated condition. Thechamber 9 is provided with an mule: pipe gection 9", which is dciachubiycon nected to the upper end of a conduit 9% by acoupling 9 The lower endof the conduit 9 is detachably connected in a well known manner to acoupling 9 which in turn is screw threaded in the inner end, or openingfor the duct 4". The pipe or conduit h and its connections with thechamber 9 and valve member -l" serve as suitable means for rigidlysupporting the chamber 9 upon the base 2 and at a suitable height toeffect the flow of the liquid through the apparatus.

11 indicates a depending dischar e pipe connected with the discharge endof the duct 4. At its lower cud, the discharge pipe 11 is connected witha delivery pipe 6 which conducts the liquid to a receiver 12, the flowof liquid through the pipe (,3 and 11 from the holders being variable. Acut oli" cock or valve 6 may be provided for the pipe 6.

12 indicates a discharge pipe leading from the receiver 12* and arrangedto convey the liquid in a substantially continuous and uniform manner tothe receiving tank 11' for the preliminary cooler ll, valvev 1'12 may beprovided for controlling the ilUW of liquid from the receiver 12 to thetank W. The receiver 12 lo preferably mounted on a standard if. lt maybe diapcnucd with if desired, in which event the liquid will beconducted directly to the tank ifi't The tank N permits the liquid"vafter treat mcnt in the holding apparatus l), to be inu xectcd 10"indicates a pipe, leading from the outer end of each pipe section l0 tothe adjacent vessel 8. As shown in the drawings, the outer end of thepipe 10" leads to and is; connected with the pipe section 8 of thevessel S by a T'II'liiIllbQ! l0 and coupling 10". The opposite or innerend of the pipe l0 is connected to the outer end of the pipe section 10"by a coupling 10 in a well known manner. The pipe 10 and their unionswith the vessels and pipc rwtt'lilUIlS 10* serve as rigid conncctiombetween the valve 10 and vessels 8, whereby the revolving movement ofthe latter is transmitted to the valve element 10 in order that thelatter will move with the vessels as a unit.

From the foregoing description it will be understood [hot the ringmember 10 and Walls of the member -l: c nstitute a valve mechanism whichcontrols the flow of the liquid through he pipcs 1O, it)", to and fromthe vessel as each opening 10 successively regiwtcr with the openings oithe ports 4", 4.

While the effectof this construction and operation is to produce amore or less variableand inter mittcnt flow of the liquid through the apparatus, theapparatus may be so proportioned to the apparatus to which it deliversas to give completely satisfactory results in connection therewith.

13 indicates a pipe or conduit leading from the pipe a and connected atits outer end to'a delivery pipe 6. A valve, prefer ably of thethree-way type may be interposed at the connection of the pipe 13 withthe pipe 10 to control the flow of the liquid to either the distributingand holding apparatus or direct to the cooler B, or to cut off the flowof the liquid entirely. The pipes 13 and 6 may be ised to conduct theliquid from the heater A to the cooler B, when it is unnecessary totreat the liquid in the distributing and holding apparatus D. The pipest3 and 13 may be formed in sections and connected together by couplings13 in a well known manner.

It will he understood that, in the system of pastcurizing liquid towhich my invention is particularly applicable and in which the liquid ismaintained at a pasteurizing temperature for a predetermined period, itis desirable to quickly and uniformly heat the liquid to thepredetermined temperature, maintain the liquid at that temperature for acertain definite length of time in order to destroy or render innocuousany germs or bacteria contained in the liquid. and finally to cool theliquid to a normal temperature; and that it is also desirable that thesesteps shall be carried out in a progressive manner. that is, that thereshall he a substantially continuous flow of the liquid to and throughthe heater, and from the heater to the holder. The holder, however, maydeliver or discharge the milk in a more or less variable andintermittent. manner. These results are all accomplished in theapparatus herein described and illustrated, as will be more fullyunderstood from the following described opcrations: The liquid isdelivered to a rcceiving tank having a discharge pipe A, which operatesas a supply means and from which it flows by gravity to the heater A. Inpassing through the heater the liquid is suddenly and uniformly raisedto the desired temperature and is discharged from the heater by means ofthe pipe 10*, which conveys the liquid to the receiving chamber 9. Asthe carrier 5 and vessels 8 carried thereby revolve, the valve openings10 in the ring valve 10 register successively with the duct 4" of thevalve member 4 and permit a predetermined quantity of the liquid to flowby gravity to each of the vessels, each valve port registering with theduct for a given period of time, in the rotary movement of the carrier,sufiicient to, at least,.

substantially fill the adjacent vessel. Likewise, the valve openings 10of the valve ring 10 register successively with the discharge duct 4"and pgrmit the automatic discharge of the vessels successively. Thevalve duct l of the valvemechanism 4 may be arranged at anyac-determined point angularly of the axis of the carrier relative to theport 4", so that the distance of travel of the vessels tron: theposition for filling to the position for emptying may be of properlength in order that the period for holding the liquid may be fixedaccording to any harticula r circumstances desired. From thisconstruction and operation it will be seen that the vessels will beautomalimdly filled and emptied at predetermined points, and that theliquid in each vessel will be held therein for a predetermined period,the extent of which depends upon the length and time of travel from theplace of filling to the place of discharge. It will be obvious that thespeed of the carrier can be changed in various ways to increase ordecrease the period between the filling and emptying of the vessels;

I am aware of the fact that it has been heretofore proposed to provideapparatus for treating or pasteurizing milk, cream or other liquids inwhich the milk was heated to a pasteurizing temperature while flowingcontinuously, was then maintained at the pasteurizing temperature for asufiicient period of time to destroy or render innocuous the bacteriawithout cooking the albumen in the milk, and without the discontinuingof the flow of the milk while being heated, and then cooling the milk,as for example as disclosed in Letters Patent of the United States No.684.319, to Frederick G. Short, and I do not lay any claim broadly to ai process of treating milk or other liquids and to apparatus such as setforth and disclosed in the said Short patent. On the contrary, I havesought to provide improved apparatus for the treating of milk or otherliquids by first heating it to a pasteurizing temperature, then holdingit at that temperature for a predetermined time. and then cooling it.

It will be noted that all walls of the conduits and receptacles in theholding mechanism, with which any liquid to be treated may come intocontact, are readily accessible for the purpose of cleaning merely bydisassembling adjaccnt parts or conduits. The importance of this in thesanitary handling of milk, for example, is well known. ther, it will benoted that the construction of the valve mechanism is such that liquidfrom the source of supply always flows in one direction through thevalve inlet duct to the vessel ducts, successively, and also alwaysflows in one direction through the valve discharge duct from the vesselducts,

intranet Successi'voly. a definite and pernnmont relation lwtwooi: thesou-roe of supply and the inlet duct through the valve mechanism and ndefinite and pormanont relation botweon the outlot duct through thevalve mechanism and tho discharge way;
